I have used truck stops and gas stations. Truck stops are generally easy in and easy out. Although so are many stations you just have to look them over before you go in. I have been in some pretty tight places but I always got out with the help of my DW. I only buy diesel at what I call good and clean stations. Most Murphy Bros. aka Wal Marts and Sams that sell diesel have fresh diesel as they pump a lot because of the price. I like Race Trac Love's etc. Truck stops will have higher price for fuel. In some areas In some areas as much as 50 cents a gallon more. A couple of years ago I put in a 60 gal. RDS aux tank and now about every third day or so I buy fuel where I want. I use Gas Buddy or any of the internet sites for the states your going through that reference diesel stations. As far as DEF you can get at truck stops or Wal Marts. I just bought a 2014 Ram a couple of weeks ago so I will start using that stuff also. Good luck
